Zoom in and out of a website

Here's how you can zoom in and out of individual websites.

Click the menu button on the right. The customization menu will open and you will see the zoom controls at the top.

Use the + button to zoom in, and the - button to zoom out. The number in the middle is the current zoom level - click it to reset the zoom to 100%. You can also see the current zoom level in the address bar:

Keyboard shortcuts: You can also use the zoom controls without a mouse. Press and hold commandCtrl while pressing + to zoom in, - to zoom out, or 0 to reset.

Tip: To set the default zoom level for all websites, try the NoSquint Plus add-on.

How to only change the size of the text

Instead of changing the size of everything, you can just change the size of the text.

Press the Alt key to temporarily bring up the traditional Firefox menus. On the menu at the top, click View, then go to Zoom.

Select Zoom Text Only. This makes the controls only change the size of text; not images.

Set a minimum text size

You can set Firefox to automatically display all text at a minimum font size. If a web page contains text that is smaller, Firefox increases the font size of the text to this minimum.

Click the menu button and choose Options.Preferences.

Select the ContentGeneral panel and go down to Language and Appearance.

In the Fonts & Colors section, click Advanced....

In the Minimum Font Size drop-down, select the minimum size in pixels in which all text must be displayed.

Click OK to save your changes.

Alternate method: If you're unable to access your font settings through the menu button, type about:config into your address bar. Search for the font.minimum-size preference and change the value to 0.
